Hello, I have a bobcat 743b that I recently purchased and noticed when going straight, the left drive is quite a bit slower than the right. I have to push the left arm all the way forward and the right arm is at least half way back. Is this an adjustment that needs to be made or do you think that I am having pump problems? There isn't any leaks and there is plenty of hydraulic fluid in machine. It is just very annoying because it moves so slow due to left drive. Thanks for any help. Jason
